The present application claims priority from japanese patent application No. 2017-128308, applied for 30/6/2017, the entire contents of which are incorporated herein by reference.
Technical Field
The present invention relates to a control device for an autonomous vehicle.
Background
The development of autonomous vehicles is constantly evolving. In addition to a vehicle that automatically performs only a part of driving operations (for example, braking operations), some autonomous vehicles also automatically perform all driving operations. In the automated driving processing device described in patent document 1 below, automated driving of an automated vehicle can be started based on an operation performed by a user on a remote operation device.
In order to ensure safety in an autonomous vehicle in which all driving operations are automatically performed, it is necessary to prevent the autonomous vehicle from starting at a time unexpected by the user (i.e., due to an erroneous operation or the like). In an automated driving processing device described in, for example, patent document 1 below, automated driving is started only when it is possible to confirm that a remote operation for starting automated driving is performed by a user who is located away from a vehicle. This prevents the user operating the remote operation device from starting automatic driving by an erroneous operation.

Disclosure of Invention
However, even if the operation for starting automated driving is made based on the intention of the user, it may be inappropriate to start automated driving at that time. For example, the following may occur: in a situation where the infant is forgotten to stay in the vehicle interior, the user who is unaware of the situation performs an operation for starting the automatic driving from the outside of the vehicle. When the automated driving vehicle is started in the above-described case, it is not desirable that the automated driving vehicle be started in a state where only the infant is carried. The same applies to a situation in which only dementia patients are present in the vehicle compartment, not infants.
The purpose of the present invention is to prevent the start of automatic driving in a situation where only an infant or the like is present in the vehicle interior.
The control device of the present invention is a control device for an autonomous vehicle, including: a communication unit that receives an external start signal for causing an autonomous vehicle to start autonomous driving and transmitted from outside the autonomous vehicle; a control unit that performs processing necessary for automatic driving; and a person determination unit that determines whether or not a person is present in a vehicle interior of the autonomous vehicle. When the person determining unit determines that a person is present in the vehicle interior, the control unit does not start the automatic driving even if the communication unit receives the external start signal.
According to the control device configured as described above, when the person determination unit determines that a person is present in the vehicle interior, the communication unit does not start the automatic driving even when the external start signal is received. That is, only when no person is present in the vehicle interior, the automatic driving is started based on the external start signal. Therefore, it is possible to reliably prevent the automatic driving from being started by the operation of the user outside the vehicle in a situation where an infant or the like is present in the vehicle interior.
According to the present invention, there is provided a control device capable of preventing the start of automatic driving in a situation where only an infant or the like is present in a vehicle interior.

Detailed Description
The present embodiment will be described below with reference to the drawings. For the sake of easy understanding, the same components are denoted by the same reference numerals as much as possible in the drawings, and redundant description is omitted.
The control device 100 according to the first embodiment is mounted on the autonomous vehicle MV and controls the autonomous vehicle MV. Before describing the control device 100, the configuration of the autonomous vehicle MV will be described with reference to fig. 1.
The autonomous vehicle MV is a vehicle capable of automatically performing all driving operations (driving, steering, and braking) required for traveling. The user can start the automatic driving of the automatic driving vehicle MV by operating the operation unit 150 provided in the cabin of the automatic driving vehicle MV. Further, the user can also start the automatic driving of the automatic driving vehicle MV by operating the external device 30 from the outside in a state where the automatic driving vehicle MV is not mounted. The external device 30 may be, for example, a mobile communication terminal carried by a user or a stationary communication terminal installed in a house where the user lives.
The autonomous vehicle MV is provided with a plurality of doors 17 for allowing a user (i.e., a passenger) to enter and exit the vehicle interior. In addition, in fig. 1, the plurality of gates 17 are represented as a single frame. Each door 17 is provided with a window glass 18. The window glass 18 is a so-called power window, and the opening degree thereof can be changed by electric power.
Although the autonomous vehicle MV is provided with a plurality of seats on which users sit, the illustration of the seats is omitted in fig. 1. A child seat 19 for seating an infant is provided in a part of the seats.
In addition to the above-described devices, the autonomous vehicle MV further includes: a human detection unit 11, an authentication device 12, an in-vehicle camera 13, an electric power steering device 14, an electric brake device 15, and a navigation system 16.
The human detection unit 11 is a device for detecting the presence of a human in the vehicle interior of the autonomous vehicle MV. As the person detecting section 11, a heat sensor is used in the present embodiment. The human detection unit 11 generates a thermal image of the vehicle interior, and transmits the image to the control device 100. Further, as the human detector 11, there can be used: the vehicle-mounted seat control device includes a camera for photographing a vehicle interior with visible light, a weight sensor for detecting the weight of an object placed on a seat, and a microphone for detecting a voice in the vehicle interior.
The authentication device 12 is a device that performs authentication processing, which is processing for confirming that a user (i.e., a person present in the vehicle interior) riding in the autonomous vehicle MV is a specific person. The authentication device 12 of the present embodiment performs authentication processing by reading information recorded in a road transport office driver's license held by a user. After that, the authentication device 12 transmits the result of the authentication process (authentication result) to the control device 100. In addition, as the authentication device 12, a device that performs authentication processing by capturing an image of the face of the user with a camera and analyzing the obtained image may be used. Further, a device that performs authentication processing by communicating with a mobile communication terminal held by a user may be used.
The in-vehicle camera 13 is a camera for photographing the periphery, particularly the front side, of the autonomous vehicle MV. The in-vehicle camera 13 is, for example, a camera using a CMOS sensor. The in-vehicle camera 13 transmits image data obtained by shooting to the control device 100. The control device 100 analyzes the image to recognize the position of an obstacle or a lane around the autonomous vehicle MV. This makes it possible to automatically perform steering and braking for avoiding a collision with an obstacle, steering for realizing travel along a lane, and the like. The image processing may be performed by an ECU provided separately from the control device 100.
The electric power steering device 14 is a device that applies a steering force generated by electric power to a steering shaft. When performing autonomous driving in the autonomous vehicle MV, the electric power steering device 14 generates all the steering force necessary for traveling along the lane without depending on the steering operation of the driver.
The operation of the electric power steering device 14 is controlled by the control device 100. Further, an ECU that controls the electric power steering device 14 may be separately provided. In the above case, the control device 100 controls the operation of the electric power steering device 14 by communicating with the ECU.
The electric brake device 15 is a device for generating a braking force from electric power and decelerating or stopping the autonomous vehicle MV. When the autonomous driving is performed in the autonomous driving vehicle MV, the electric brake device 15 automatically generates a braking force without depending on the braking operation by the driver. The operation of the electric brake device 15 is controlled by the control device 100. Further, an ECU that controls the electric brake device 15 may be separately provided. In the above case, the control device 100 controls the operation of the electric brake device 15 by communicating with the ECU.
As the electric brake device 15, for example, regenerative braking using an electric motor may be used, or hydraulic braking may be used. That is, electric brake device 15 may be any device that generates the braking force of autonomous vehicle MV based on a signal from control device 100.
The navigation system 16 is a system that determines the current position where the autonomous vehicle MV travels by GPS. The navigation system 16 can generate a route to be traveled by the autonomous vehicle MV to reach the destination, and display the route to the user or guide the autonomous vehicle MV to travel automatically along the route.
Next, the configuration of the control device 100 will be described with reference to fig. 1. The control device 100 is configured as a computer system having a CPU, a ROM, a RAM, and the like. The control device 100 includes a communication unit 110, a person determination unit 120, an authentication unit 130, and a control unit 140 as functional control blocks. Further, the control device 100 includes, as peripheral devices connected to the main body portion of the computer system, an operation section 150, a door state detection section 160, a window opening degree detection section 170, and a seat state detection section 180.
The control device 100 configured as described above may be configured as a single computer system, but may be configured in such a manner that a plurality of computer systems cooperate with each other and the entire control device 100 functions. Further, the following manner is also possible: a part or the whole of the control device 100 is provided at a position different from the autonomous vehicle MV, and controls autonomous driving of the autonomous vehicle MV by communicating with the autonomous vehicle MV.
The communication unit 110 is a part configured as a communication interface with the outside. The communication unit 110 receives an external start signal transmitted from the external device 30. The external communication signal is a signal for starting the automated driving of the automated driving vehicle MV. When the user performs an operation for starting the automated driving at the external device 30, an external start signal is transmitted from the external device 30. When the communication unit 110 receives the external start signal, the control device 100 performs a process for starting the automated driving of the automated driving vehicle MV. In addition, even if the communication unit 110 receives an external start signal, the control device 100 may not start the automatic driving. This will be described later.
The person determination unit 120 is a unit that determines whether or not a person is present in the vehicle interior of the autonomous vehicle MV. The person determination unit 120 determines whether or not a person is present in the vehicle interior based on the thermal image in the vehicle interior, which is the information transmitted from the previously described person detection unit 11. Further, the human detection unit 11 may determine whether or not a human is present, and the human detection unit 11 may receive the determination result.
The authentication unit 130 is a part that confirms that a user (i.e., a person present in the vehicle interior) riding in the autonomous vehicle MV is a specific person. The authentication unit 130 receives the information transmitted from the authentication device 12 described above, i.e., the result of the authentication process, and thereby performs the confirmation. The authentication unit 130 may be configured as a part that receives only the result of the authentication process performed by the authentication device 12, or may be configured as a part that performs the authentication process based on information (for example, information of a driver's license) transmitted from the authentication device 12.
The control unit 140 is a part that performs processing necessary for automatic driving. The control unit 140 performs automatic driving of the autonomous vehicle MV by controlling the driving force, the electric power steering 14, and the electric brake device 15, and the like, based on the analysis result of the image obtained by the onboard camera 13, information obtained from the navigation system, and the like.
The operation unit 150 is a part that receives an operation by a user. The above-described operation is an operation for causing the autonomous vehicle MV to start autonomous driving. The operation unit 150 is provided in the vehicle compartment. When a user in the vehicle cabin wants to start the automated driving, the user does not operate the external device 30 but operates the operation portion 150.
The "operation for starting the automated driving" means an operation for actually starting control related to driving, steering, and braking of the automated driving vehicle MV when the operation is performed. Therefore, for example, the operation of setting the target value only in the navigation system 16 is not included in the above operation.
The operation unit 150 is a push button switch in the present embodiment. The operation unit 150 may be a numeric button for allowing the user to input a predetermined number in accordance with a voice guidance. The operation unit 150 may be a microphone for receiving a voice uttered by the user. In this case, control device 100 starts the automatic driving by recognizing the voice input to operation unit 150.
The operation unit 150 may be one of the above-described embodiments, or may be a combination of a plurality of the embodiments. For example, the operation unit 150 may include both a push button switch and a microphone for receiving voice, and the automatic driving may be started only when both are operated.
In any case, it is preferable that the operation of the operation portion 150 for starting the automatic driving is an operation that is difficult for an infant, a dementia patient, or the like.
The operation unit 150 is configured to be incapable of at least a part of operations by a person outside the autonomous vehicle MV. That is, in a state where the user is not riding on the automated driving vehicle MV, the user cannot start automated driving by, for example, inserting a hand from the gap of the opened window glass 18 to operate the operation unit 150.
The structure of the operation unit 150 includes the following: for example, the push button switch is provided near the center console, under the seat, or the like, at a position away from the door 17. Further, the following structures are enumerated: the operation to the operation unit 150 is received only when the seat belt is fastened and the weight sensor of the seat detects the weight. Further, the following structures are enumerated: the microphone is set to receive only the voice uttered in the vehicle interior, on the basis of setting the microphone for receiving the voice as a directional microphone.
In addition, when a plurality of operations are required as the operation for starting the automated driving, it is sufficient if only a part of the plurality of operations cannot be performed by a person outside the automated driving vehicle MV.
The door state detection unit 160 is a sensor for detecting the open/close state of the door 17 provided in the autonomous vehicle MV. The door state detection unit 160 is disposed to be able to detect the open/close state of each door 17. The detection state of each door 17 detected by the door state detection unit 160 is transmitted to the control device 100.
The window opening degree detecting unit 170 is a sensor for detecting the opening degree of the window glass 18 provided in each door 17. The window opening degree detection unit 170 is disposed to be able to detect the opening degree of each window glass 18. The opening degree of each window glass 18 detected by the window opening degree detecting unit 170 is transmitted to the control device 100.
The seat state detection unit 180 is a sensor for detecting the presence of a person in the child seat 19. The seat state detector 180 of the present embodiment is a weight sensor provided in the child seat 19. When an object having a predetermined weight or more is placed on the child seat 19, the seat state detection unit 180 detects the object as a human (specifically, an infant). The presence or absence of a person detected by the seat state detection unit 180 is transmitted to the control device 100.
The seat state detector 180 as a weight sensor may be provided not in the child seat 19 but in a seat to which the child seat 19 is attached. For example, it is conceivable that a mechanism for measuring the weight of an object placed on the seat is incorporated in a portion of the seat that serves as the attachment surface of the child seat 19. In this case, the seat state detection unit 180 detects the presence of a person in the child seat 19 based on a value obtained by subtracting the weight of the child seat 19 from the weight measured by the weight sensor. The seat state detector 180 may be configured not as a weight sensor but as a temperature sensor.
Consider the following situation: in a situation where the infant is forgotten to stay in the vehicle interior, the user who is not aware of the situation operates the external device 30 from the outside of the vehicle, and starts the automatic driving. In this case, the infant who cannot cope with the change in the situation by his or her own judgment is undesirably left in the vehicle interior alone. The same applies to a situation in which only dementia patients are present in the vehicle compartment, not infants.
Therefore, the control device 100 of the present embodiment performs the processing described below to prevent the start of automatic driving in a situation where only an infant or the like is present in the vehicle interior.
The control device 100 repeatedly executes a series of processing shown in fig. 2 every time a predetermined control cycle elapses. In the first step S01 of this process, it is determined whether or not a person is present in the vehicle interior. This determination is made by the person determination unit 120. When it is determined that a person is present in the vehicle compartment, the process proceeds to step S02.
In step S02, the process proceeds to a mode in which automatic driving from the outside is rejected. Thereafter, even if the communication unit 110 receives an external start signal transmitted from the external device 30, the control unit 140 does not start the automated driving. Therefore, in order for the user to start the automated driving, it is necessary to operate the operation unit 150 in the vehicle interior in a state where the user is riding on the automated driving vehicle MV.
In step S03 after step S02, the authentication unit 130 performs an authentication process. When the result of the authentication process is qualified, that is, when it can be confirmed that the user riding in the autonomous vehicle MV is a specific person, the process proceeds to step S04. When the result of the authentication process is not qualified, that is, when it cannot be confirmed that the user riding on the autonomous vehicle MV is a specific person, the series of processes shown in fig. 2 is ended. Note that the process may not be passed through step S03, and the process may always proceed from step S02 to step S04.
In step S04, it is determined whether or not the user has performed an operation on operation unit 150, that is, an operation for starting automated driving. When the operation to the operation unit 150 is not performed, the series of processing shown in fig. 2 is ended. When the operation to the operation unit 150 is performed, the process proceeds to step S05. In step S05, the control unit 140 performs a process of starting the automatic driving. Thereafter, the control unit 140 performs automatic driving.
In step S01, when it is determined that no person is present in the vehicle interior, the process proceeds to step S06. In step S06, the process proceeds to a mode in which the automatic driving is allowed to be started from the outside. Thereafter, when the communication unit 110 receives an external start signal transmitted from the external device 30, the control unit 140 starts the automated driving.
In step S07 after step S06, it is determined whether or not the communication unit 110 has received an external start signal. When the communication unit 110 receives the external start signal, the process proceeds to step S05. Thereafter, as described above, the control unit 140 performs the automatic driving. When the communication section 110 does not receive the external start signal in step S07, the series of processing shown in fig. 2 is ended.
As described above, in the present embodiment, when the person determining unit 120 determines that a person is present in the vehicle interior, the control unit 140 does not start the automatic driving even if the communication unit 110 receives the external start signal. That is, only when no person is present in the vehicle interior, the automatic driving is started based on the external start signal from the external device 30. Therefore, it is possible to reliably prevent the automatic driving from being started by the operation of the user outside the vehicle in a situation where an infant or the like is present in the vehicle interior.
In the present embodiment, when the person determining unit 120 determines that a person is present in the vehicle interior, the control unit 140 starts the automatic driving only when the operation unit 150 is operated. Therefore, the automatic driving is started only when a person who can perform an operation on the operation unit 150 (that is, a person who is not an infant, a dementia patient, or the like) is present in the vehicle interior by his or her own judgment. With the above configuration, it is possible to more reliably prevent the start of automatic driving by an operation of a user outside the vehicle.
As described above, the operation unit 150 is configured such that at least a part of the operations cannot be performed by the person outside the autonomous vehicle MV. This prevents the user outside the vehicle from extending the arm operation unit 150 from the door 17 into the vehicle to start the automatic driving.
A second embodiment will be described with reference to fig. 3. The present embodiment differs from the first embodiment (fig. 2) only in the manner of processing performed by the control device 100, and is otherwise the same as the first embodiment. The series of processing shown in fig. 3 is repeatedly executed by the control device 100 instead of the series of processing shown in fig. 2. This processing adds step S11 and step S12 to the series of processing shown in fig. 2. Hereinafter, description will be given mainly of points different from the first embodiment, and description of points common to the first embodiment will be omitted as appropriate.
When the operation to operation unit 150 is performed in step S04, the process proceeds to step S11. In step S11, it is determined whether the door 17 is in the closed state. This determination is made based on the detection result of the door state detection section 160. When the door 17 is in the closed state, the process proceeds to step S05. On the other hand, when the door 17 is not in the closed state, that is, when the door 17 is in the open state, the automatic driving is not started, and the series of processing shown in fig. 3 is ended. In this case, a message that the automatic driving cannot be started because the door 17 is opened may be notified to the user in the vehicle interior by voice or the like.
In step S07, when the communication unit 110 receives the external start signal, the process proceeds to step S12. In step S12, it is determined whether the door 17 is in the closed state. This determination is made based on the detection result of the door state detection section 160. When the door 17 is in the closed state, the process proceeds to step S05. On the other hand, when the door 17 is not in the closed state, that is, when the door 17 is in the open state, the automatic driving is not started, and the series of processing shown in fig. 3 is ended.
As described above, in the present embodiment, even when the operation to the operation unit 150 is performed, the control unit 140 does not start the automated driving when the door state detection unit 160 detects that the door 17 is in the open state. This can more reliably prevent the user outside the vehicle compartment from extending the arm operation unit 150 from the door 17 into the vehicle compartment and starting the automatic driving.
In the present embodiment, even when the external start signal is received in a state where the user is present in the vehicle interior, the control unit 140 does not start the automated driving when the door state detection unit 160 detects that the door 17 is in the open state. This prevents the autonomous vehicle MV from starting to travel while the door 17 is kept open.
A third embodiment will be described with reference to fig. 4. In the present embodiment, the mode of processing performed only by the control device 100 is different from that of the second embodiment (fig. 3), and the other steps are the same as those of the second embodiment. The series of processing shown in fig. 4 is repeatedly executed by the control device 100 instead of the series of processing shown in fig. 3. This processing adds step S13 to the series of processing shown in fig. 3. Hereinafter, description will be given mainly of points different from the second embodiment, and description of points common to the second embodiment will be omitted as appropriate.
When the door 17 is in the closed state in step S11, the process proceeds to step S13. In step S13, it is determined whether or not the opening degree of the window glass 18 is equal to or smaller than a predetermined opening degree. This determination is made based on the detection result of the window opening degree detection section 170. When the opening degree of the window glass 18 is equal to or smaller than the predetermined opening degree, the process proceeds to step S05. On the other hand, when the opening degree of the window glass 18 is larger than the predetermined opening degree, the automatic driving is not started, and the series of processing shown in fig. 4 is ended.
The "predetermined opening degree" is an opening degree that is set in advance to such an extent that the user outside the vehicle cannot operate the operation unit 150 through the gap of the window glass 18. Therefore, it is preferable to appropriately set the predetermined opening degree based on the mode and position of the operation unit 150. For example, when a microphone that detects a voice in the vehicle interior is used as the operation unit 150, the predetermined opening degree is set to "fully closed" so that the voice from the outside does not reach the microphone in the vehicle interior.
The operation that cannot be performed when the opening degree of the window glass 18 is equal to or smaller than the predetermined opening degree may be all operations performed on the operation unit 150, but may be only a part of a plurality of operations necessary for starting the automatic driving. In any case, it is sufficient that the outside user cannot operate the operation portion 150 from the gap of the window glass 18 to start the automatic driving.
As described above, in the present embodiment, even when the door state detection unit 160 detects that the door 17 is in the closed state while the operation unit 150 is being operated, the control unit 140 does not start the automatic driving if the opening degree of the window glass 18 detected by the window opening degree detection unit 170 is larger than the predetermined opening degree. This can reliably prevent the outside user from operating the operation portion 150 from the gap of the window glass 18 to start the automatic driving.
A fourth embodiment will be described with reference to fig. 5. In the present embodiment, the mode of processing executed only by the control device 100 is different from that of the first embodiment (fig. 2), and the other steps are the same as those of the first embodiment. The series of processes shown in fig. 5 is repeatedly executed by control device 100 after the start of automated driving by at least one operation on operation unit 150, that is, after step S05 in fig. 2 is performed.
In the first step S21, it is determined whether or not the door 17 is in an open state. This determination is made based on the detection result of the door state detection section 160. When the door 17 is not in the open state, that is, when the door 17 is in the closed state, the series of processes shown in fig. 5 is ended. On the other hand, when the door 17 is in the open state, the process proceeds to step S22.
In step S22, processing for automatic limp home running is performed. The automatic limp home running is a process for stopping the running autonomous vehicle MV at a safe place. The state in which the automatic retreat running is performed may be referred to as a state in which automatic driving is restricted. When the autonomous vehicle MV has stopped in the state shifted to step S22, the autonomous vehicle MV is restricted from subsequent autonomous driving, and the stopped state of the autonomous vehicle MV is maintained.
As described above, in the present embodiment, when the door state detection unit 160 detects that the door 17 is in the open state after the operation to the operation unit 150 is performed, the control unit 140 restricts the automatic driving. This prevents continuation of automated driving with only infants and young children loaded, for example, when only the adult passenger opens the door 17 to get off the vehicle MV after automated driving is started with infants and young children loaded in the vehicle interior, and when only the adult passenger gets off the vehicle from the automated driving vehicle MV.
A fifth embodiment will be described with reference to fig. 6. The present embodiment differs from the first embodiment (fig. 2) only in the manner of processing performed by the control device 100, and is otherwise the same as the first embodiment. The series of processing shown in fig. 6 is repeatedly executed by the control device 100 instead of the series of processing shown in fig. 2. This processing adds steps S31, S32, S33 to the series of processing shown in fig. 1. Hereinafter, description will be given mainly of points different from the first embodiment, and description of points common to the first embodiment will be omitted as appropriate.
In step S31, which is performed prior to step S01, it is determined whether the child seat 19 is occupied. This determination is made based on the detection result of the seat state detection unit 180. When it is determined that there is no person in the child seat 19, the process proceeds to step S01. When it is determined that a person is present in the child seat 19, the process proceeds to step S32.
In step S32, it is determined whether or not another person is present in the vehicle interior, that is, whether or not a person different from the person seated in the child seat 19 is present in the vehicle interior. This determination is made by the person determining unit 120 based on the detection result of the person detecting unit 11. When it is determined that another person is present in the vehicle compartment, the process proceeds to step S02. On the other hand, when it is determined that no other person is present in the vehicle interior, that is, when it is determined that only the infant seated in the child seat 19 is present in the vehicle interior, the process proceeds to step S33. In step S33, the automatic driving is prohibited from being executed thereafter. After that, the series of processes shown in fig. 6 is ended.
As described above, in the present embodiment, when the seat state detection unit 180 detects that a person is present in the child seat 19 and the person determination unit 120 determines that no other person is present in the vehicle interior, the control unit 140 does not start the automatic driving process. Specifically, when the communication section 110 receives an external start signal, or when an operation to the operation section 150 is performed, the control section 140 does not start the automatic driving.
In the present embodiment, by performing the above control, it is more reliably prevented that the automatic driving is started in a situation where only the infant is present in the vehicle interior.
The present embodiment has been described above with reference to specific examples. However, the present invention is not limited to the specific examples. Even if a person skilled in the art appropriately changes the design of the above specific examples, the specific examples are included in the scope of the present invention as long as the characteristics of the present invention are included. The elements included in the specific examples, and the arrangement, conditions, shapes, and the like thereof are not limited to the examples and may be appropriately modified. Each element included in each of the specific examples described above may be appropriately combined and changed as long as no technical contradiction occurs.
